Specification of Letters Patent.

Patented Feb. 5, T91...

Application filed February 16, 191?. Serial No. 149,028.

To all whom it may concern: 7

Be it known that I, ADOLPH F. Crrnrsr MAS, a citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, have invented a certain new and useful Improvement in Governors, 01": which the following is a specification.

This invention relates to an improvement in governors, and especially to governors for oil engines in which the admission of fuel to the engine is controlled by means of an oil injecting pump but the invention may be applied equally well to a steam engine in which the admission of steam is controlled by means of a valve.

This invention further relates to improvements in the construction disclosed in my eopending application Serial Number 30,508, tiled May twenty-sixth, nineteen hundred and fifteen.

The object of this invention is to provide means for quickly and easily varying the angle of lead of the eccentric pin to the crank so that a charge of oil or elastic fluid may be admitted to the cylinder at precisely the proper time to obtain maximum ciliciency.

It is obvious that with various grades and types of fuel oils now available for use in engines the time'whic'h it takes to fully vaporize and ignite them varies very greatly between a light distillate and a heavy residual oil. For this reason it is necessary to inject the oil into the cylinder at diiterent times in order that it may be fully vaporized and ignited just as the crank passes the dead center. For heavier oils the lead must be increased so that a longer time will elapse between the instant of injection and the time that the crank passes the dead center and for lighter or more easily vaporized oils the lead must be decreased in order that this time may be shortened. While the wide range of adjustment of the lead is not required in steam engines, still with different Iorms of valves and different speeds used in these engines an adjustment of the lead sometimes becomes necessary.

With these and other objects in view, my invention consists in the features of con struction and operation set forth in the following specification and claims and illustrated in the annexed drawings.

In the drawings forming a part of this application,

Figure l shows a side elevation of my improved governor, and

Fig. 2, an enlarged view of the same, also shown in side elevation.

The construction sought to be claimed comprises a flywheel 1 having a weight 2 forming a centrifugal element, pivoted eccentrically to the flywheel at 10 and which is held in its inner position by a spring 3. An arm 4 pivoted eccentrically to the flywheel at 11 is connected to the weight 2 by means of a link 5. The arm 4 is enlarged in its middle section and is bored to receive a flanged disk 6 held securely in place in the eccentric arm 4 by means of a clamping screw 7. Mourited rigidly on this disk (3 is a pin 8 to which a rod 9 is attached which at its opposite end (not shown) may be attached to any form of valve mechanism or fuel pump. With the disk 6 clamped in position in the arm 4 this construction operates in a manner similar to the construction disclosed in the above mentioned co-pending application, the throw of the pin 8 being governed by the position of the centrifugal member 2. Should it be desired to advance or retard the lead of the pin 8 it is merely necessary to loosen the clamping screw '4' and rotate the disk 6 slightly forwardly or backwardly in the bore contained in the arm 4, after which the clamping screw 7 may be tightened with the pin 8 and disk 6 in their new positions.

It will be seen from the above description that a mechanism has thus been provided by means of which the angle of lead of the pin 8 may be very easily and quickly readjusted.

It is to be understood that while the present showing and description disclose only one specific embodiment of my present in vention, other forms and modifications are included within the spirit and scope of the same, as expressed in the appended claims.

What I claim is:

1. In a speed governor for engines, an arm mounted eccentrically of a fly wheel, said arm carrying a disk, a pin mounted upon said disk and said disk being adapted to be rotated in said arm.

' 2. In a speed governor for engines, a centrifugal member adapted to vary the eccentricity of anarm, a rotatable disk mounted in said arm, said diskcarrying an eccentric pin. V

3. In a speed governor for engines, a centrifugal member adapted to vary the eccentricit Y of an arm said arm bein )rovided element. 7

5. In a speed governor'for engines, a centrifugal member adapted to vary the eccentricityof an'arm a rotatable disk, a pin mounted'ecce'ntrically in said disk, 'means for clamping said disk in said arm and means controlling the admission of fuel to said engine connected to said pin.

6. In a speed governor for engines, a centrifugal member adapted to vary the eccentricity of an-arm, said-arm being provided with an opening, a disk adjustably held in said opening carrying an eccentric pin, whereby the pin may be manually adjusted in said arm to vary the angle of lead of the pin.

7. In a speed governor for engines, a centrifugal'member'adapted to vary the eccentricity of an arm, said arm being provided with an opening, a disk adjustably held in said opening carrying an eccentric pin, whereby the pin may be manually adjusted in said arm to vary theangle of lead of the pin and automatically adjusted by movement of said arm to vary its throw.

In testimony whereof, I' have hereunto set my hand.

ADOLPI-I'F. CHRISTMAS.
